Architectural principles influence and shape the way you design and deliver a SATRE-aligned TRE. They are a set of guiding considerations that sit above any specific architectural requirement, and can be applied across the entire architecture.
They consist of the following parts:
Statement: A singular sentence that summarises the principle
Rationale: Justification as to why this principle is important for the specification
Implications: Things you need to consider or do to practise this principle
